Tyre Change (again)

[HillWalker]

So yesterday after months of deliberating I finally got some non runflats fitted on the 35is, I don't like spending money and much less to spend it unnecessarily, so to have to pay nearly £700 for a set of tyres that I didn't need seemed ridiculous (especially to the wife) but being only to well aware of the idiosyncrasies of the runflats and persuaded by all the posts I've read on here, and despite the one or two that said they found the runflats ok (ronk !!) I bit the bullet.

Was it worth the expense, well I drove to the tyre fitters in what felt like a go kart on the local bumpy roads and drove home in what felt like a 5 series in comparison, so by the time I got home I'd realised they were much more comfortable and a lot quieter, then the crowning glory, in the evening went out for a fastish drive on some local roads I know well and it was so much more confidence inspiring, it felt planted on the road not jiggling about on every ripple and able to keep my foot in instead of having to ease off. So a big thank you to all those that convinced me to go for it, money well spent.

P.S. the 5000 mile old runflats are for sale in the wheels/tyres section if anybody's interested after all that.

Sorry tyres for sale in the Buy/Sell Section

Probably the best mod you can do to this car. Like buying a new car.

I had some part worn run flats, just threw them away. Wouldn't want to inflict misery of them on someone else.

HillWalker Enjoy.
flybobbie Agree x 4.

 

[buzyg]

A wise choice enjoy the new driving experience.

After much deliberation I swopped out my Bridgestone run flats for MPS4 non run flats on my 35is a fortnight ago. As many have said it has totally transformed the car in all respects.

I put some non runflat goodyear's on my rears without changing the fronts. Handling was pretty unstable at around 70-80mph which was a bit unsettling. Got a puncture 2 weeks after fitting them so binned them and went back to runflats :roll:

 

[HillWalker]

You should never mix runflats with non runflats, you should have binned the other two runflats instead, would have been much better.

Why ? :? Have you tried it ?
Its not illegal or a MOT fail & after reading countless times on the forum how it should never be done purely for my own amusement the last 8 weeks ive been running a set of 19inch alloys on my E86 with non-runflat rears (5.5mm) & runflat fronts (7mm)
It drives faultlessly & there is no way anyone would be able to tell .
Twice ive switched back to back between another wheelset with 6mm MPSS on (19s) & there is nothing to divide the two in terms of
grip , handling & steering on spirited backroad drives & Mway up to 85 .
I'm not saying its the way forward but its certainly not the catastrophe many would suggest

Yep , i was surprised too when all the talk suggests the complete opposite , i guess suspension age , tyre age / brand & of course tyre pressures play a part :wink: has been quite a revelation

Ive just stumbled on this post and don’t want to be the only soldier in the column in step, but after all the positives I will probably join the ranks wehen the time comes.
The handling thing is well documented but it’s the puncture thing that bothers me - a mini compressor and a can of gunk was ok for cars without TPMS sensors but i don’t want to wreck a tpms sensor unecessarily.

May I suggest that disabling a car by using runflats in order not to damage the TPMS sensors is a poor exchange?

May I suggest that as someone who sticks vehemently to the BMW handbook, argues until he’s blue in the face that that is what one should do, then argues vehemently for non run flats, the exact opposite of what the handbook says, ermmmmm....shuts up....? Maybe...perhaps.... :wink:

 

[ronk]

Im not sure what you mean Busterboo?

The Z4 M series had non run flats, a mini compressor and a can of gunk - they didn’t have the Tpms sensors tho‘

My question is how would a can of gunk effect the tpms sensors (about £60 each I think)

Have you had any experience of the fix if punctured?

 

[HillWalker]

If the worst should happen and I did get a puncture, I would happily pay the £60 if needed for a new TPMS for the improvement the non runflats have made. Remember if you drive any distance on a runflat it needs to be replaced any way so with some gunk in a ordinary tyre to get to a repairers it would still work out cheaper.

 

[Busterboo]

Sorry, ronk, I misunderstood your original post.

I think this is because the rears are non-runflats? I think they make the biggest difference and you're sitting way closer to the rear wheels than the fronts?

I would also add that tyres need to be replaced in pairs (if you don't already know), so you shouldn't have runflat and non-runflat on the same axel. This is when you shouldn't be mixed...
